Abstract

The invention discloses a mixed-metal complex illuminating white light. The structure of the luminescence center of the complex is EuAg3 (PyNTB) 2. The invention also discloses a preparation method of the mixed-metal complex: the mixed-metal complex illuminating white light is prepared by transition metal salts, rare earth metal salts and PyNTB ligands with the mole ratio is 6:1:2 by adopting appropriate methods (e.g. stratified diffusion, natural volatilization, hydrothermal reaction and the like). White light emission obtained from the complex in the invention are not required to be treated with light diffraction and light mixing of three primary colors (red, green and blue) in the traditional method for obtaining the white light, therefore, the waste of light energy can be avoided. As the whole luminescence process is the energy transition inside the complex, theoretically, the shining efficiency is quite high and has bright application future.

Description

technical field

[0001] The invention relates to a white light-emitting mixed metal complex and a preparation method thereof, in particular to a white light mixed complex based on a rare earth-transition metal and a PyNTB tripod ligand and a preparation method thereof. Background technique

[0002] In recent years, new luminescent materials have become a new growth point in the fields of flat-panel display backlight and general solid-state luminescent lighting. Among them, small organic molecules and metal-organic complex light-emitting materials have the characteristics of strong chemical modification, wide selection range, easy purification, high luminous efficiency, and the ability to produce red, green, blue and other colors of light. It has opened up a new world in the field of monochromatic luminescence and composite luminescence. But so far, the examples of using the above materials to generate white light are basically limited to the formation of exciplexes or the us...
